REPT A-Grade 104Ah LiFePO4 Cell

The REPT 104Ah cell is specified as an A-Grade LiFePO4 cell, making it suitable for professional battery-pack assembly.

A-Grade cells are preferred for applications where consistent cell quality and electrical characteristics are important.

For multi-cell battery construction, it is recommended to match cells according to:

Voltage

Capacity

Internal resistance

State of charge

Overall cell condition

Proper matching can help improve cell consistency and the performance of the completed battery pack.

0.28mΩ Internal Resistance

The updated internal resistance specification for this cell is:

0.28mΩ

Low internal resistance can help minimize voltage drop and reduce internal heat generation during current flow.

Actual resistance measurements can vary depending on:

Cell temperature

State of charge

Testing equipment

Measurement method

Cell condition

For professional battery assembly, cells with closely matched resistance are recommended.

6000 Cycle Life

The REPT 104Ah cell is specified with:

6000 Cycle Life

This makes it suitable for applications requiring frequent charging and discharging, including:

Solar energy storage

Home backup

Inverter batteries

UPS systems

Commercial energy storage

EV applications

Portable power stations

Off-grid systems

Actual cycle life depends on operating conditions such as depth of discharge, charging voltage, current, temperature, BMS settings and cell balancing.

High-Power Discharge Capability

According to the provided specifications, the cell supports:

3C Continuous Discharge

For a 104Ah cell:

3C = 312A

The specification also indicates:

Up to 5C Instant/Pulse Discharge

For a 104Ah cell:

5C = 520A

The 5C figure should be treated as an instant/pulse rating, not a continuous operating current.

The actual allowable current of a complete battery will depend on the BMS, cables, busbars, terminals, fuse, temperature and overall battery design.

104Ah Capacity & Nominal Energy

One cell provides:

3.2V × 104Ah = 332.8Wh

Therefore, the cell has approximately:

332.8Wh / 0.333kWh Nominal Energy

The total energy of a battery pack depends on its series and parallel configuration.

Battery Configuration Examples

4S 104Ah – 12.8V 104Ah
